Final answer:
The total price for a sheet of 20 commemorative stamps at 39 cents per stamp is $7.80.
Step-by-step explanation:
The question is regarding the price of a sheet of commemorative stamps, which are sold in sheets of 20 stamps at 39 cents each. To find the total price for one sheet, we need to multiply the cost of one stamp by the number of stamps on the sheet. Therefore, the calculation will be 39 cents per stamp multiplied by 20 stamps.
Let's do the calculation:
- 39 cents/stamp × 20 stamps/sheet = 780 cents/sheet
To convert cents into dollars, we need to divide by 100, because there are 100 cents in one dollar.
- 780 cents ÷ 100 cents/dollar = $7.80
So, the price for a sheet of 20 stamps at 39 cents per stamp is $7.80.
